Paths may start with a '~' to expand to the user's home directory. - This plugin requires inotify support in your Linux kernel and the [[http://hackage.haskell.org/package/hinotify/][hinotify]] package. To activate, pass the =with_inotify= flag during compilation. - Example: #+begin_src haskell Run Mail [("inbox", "~/var/mail/inbox"), ("lists", "~/var/mail/lists")] "mail" #+end_src ** =MailX Args Opts Alias= - Args: list of maildirs in form =[("name1","path1","color1"),...]=. Paths may start with a '~' to expand to the user's home directory. When mails are present, counts are displayed with the given name and color. - Opts is a possibly empty list of options, as flags. Possible values: -d dir --dir dir a string giving the base directory where maildir files with a relative path live. -p prefix --prefix prefix a string giving a prefix for the list of displayed mail counts -s suffix --suffix suffix a string giving a suffix for the list of displayed mail counts - This plugin requires inotify support in your Linux kernel and the [[http://hackage.haskell.org/package/hinotify/][hinotify]] package. To activate, pass the =with_inotify= flag during compilation. - Example: #+begin_src haskell Run MailX [("I", "inbox", "green"), ("L", "lists", "orange")] ["-d", "~/var/mail", "-p", " ", "-s", " "] "mail" #+end_src ** =MBox Mboxes Opts Alias= - Mboxes a list of mbox files of the form =[("name", "path", "color")]=, where name is the displayed name, path the absolute or relative (to BaseDir) path of the mbox file, and color the color to use to display the mail count (use an empty string for the default). - Opts is a possibly empty list of options, as flags. Possible values: -a --all (no arg) Show all mailboxes, even if empty. -u (no arg) Show only the mailboxes' names, sans counts. -d dir --dir dir a string giving the base directory where mbox files with a relative path live. -p prefix --prefix prefix a string giving a prefix for the list of displayed mail counts -s suffix --suffix suffix a string giving a suffix for the list of displayed mail counts - Paths may start with a '~' to expand to the user's home directory. - This plugin requires inotify support in your Linux kernel and the [[http://hackage.haskell.org/package/hinotify/][hinotify]] package. To activate, pass the =with_inotify= flag during compilation. - Example. The following command look for mails in =/var/mail/inbox= and =~/foo/mbox=, and will put a space in front of the printed string (when it's not empty); it can be used in the template with the alias =mbox=: #+begin_src haskell Run MBox [("I ", "inbox", "red"), ("O ", "~/foo/mbox", "")] ["-d", "/var/mail/", "-p", " "] "mbox" #+end_src ** =NotmuchMail Alias Args Rate= This plugin checks for new mail, provided that this mail is indexed by =notmuch=. In the =notmuch= spirit, this plugin checks for new *threads* and not new individual messages. - Alias: What name the plugin should have in your template string. - Args: A list of =MailItem= s of the form #+begin_src haskell [ MailItem "name" "address" "query" ... ] #+end_src or, using explicit record syntax: #+begin_src haskell [ MailItem { name = "name" , address = "address" , query = "query" } ... ] #+end_src where - =name= is what gets printed in the status bar before the number of new threads. - =address= is the e-mail address of the recipient, i.e. we only query mail that was send to this particular address (in more concrete terms, we pass the address to the =to:= constructor when performing the search). If =address= is empty, we search through all unread mail, regardless of whom it was sent to. - =query= is funneled to =notmuch search= verbatim. For the general query syntax, consult =notmuch search --help=, as well as =notmuch-search-terms(7)=. Note that the =unread= tag is *always* added in front of the query and composed with it via an *and*. - Rate: Rate with which to update the plugin (in deciseconds). - Example: - A single =MailItem= that displays all unread threads from the given address: #+begin_src haskell MailItem "mbs:" "soliditsallgood@mailbox.org" "" #+end_src - A single =MailItem= that displays all unread threads with "[My-Subject]" somewhere in the title: #+begin_src haskell MailItem "S:" "" "subject:[My-Subject]" #+end_src - A full example of a =NotmuchMail= configuration: #+begin_src haskell Run NotmuchMail "mail" -- name for the template string [ -- All unread mail to the below address, but nothing that's tagged -- with @lists@ or @haskell@. MailItem "mbs:" "soliditsallgood@mailbox.org" "not tag:lists and not tag:haskell" -- All unread mail that has @[Haskell-Cafe]@ in the subject line. , MailItem "C:" "" "subject:[Haskell-Cafe]" -- All unread mail that's tagged as @lists@, but not @haskell@. , MailItem "H:" "" "tag:lists and not tag:haskell" ] 600 -- update every 60 seconds #+end_src ** =XPropertyLog PropName= - Aliases to =PropName= - Reads the X property named by =PropName= (a string) and displays its value. The [[https://github.com/jaor/xmobar/raw/master/examples/xmonadpropwrite.hs][examples/xmonadpropwrite.hs script]] in xmobar's distribution can be used to set the given property from the output of any other program or script. ** =UnsafeXPropertyLog PropName= - Aliases to =PropName= - Same as =XPropertyLog=, but the input is not filtered to avoid injection of actions (cf. =UnsafeXMonadLog=). The program writing the value of the read property is responsible of performing any needed cleanups. ** =NamedXPropertyLog PropName Alias= - Aliases to =Alias= - Same as =XPropertyLog=, but a custom alias can be specified. ** =UnsafeNamedXPropertyLog PropName Alias= - Aliases to =Alias= - Same as =UnsafeXPropertyLog=, but a custom alias can be specified. ** =Brightness Args RefreshRate= - Aliases to =bright= - Args: default monitor arguments, plus the following specif ones: - =-D=: directory in =/sys/class/backlight/= with files in it (default: "acpi_video0") - =-C=: file with the current brightness (default: actual_brightness) - =-M=: file with the maximum brightness (default: max_brightness) - =--brightness-icon-pattern=: dynamic string for current brightness in =ipat=. - Variables that can be used with the =-t/--template= argument: =vbar=, =percent=, =bar=, =ipat= - Default template: =<percent>= - Example: #+begin_src haskell Run Brightness ["-t", "<bar>"] 60 #+end_src ** =Kbd Opts= - Registers to XKB/X11-Events and output the currently active keyboard layout. Supports replacement of layout names. - Aliases to =kbd= - Opts is a list of tuples: - first element of the tuple is the search string - second element of the tuple is the corresponding replacement - Example: #+begin_src haskell Run Kbd [("us(dvorak)", "DV"), ("us", "US")] #+end_src ** =Locks= - Displays the status of Caps Lock, Num Lock and Scroll Lock. - Aliases to =locks= - Example: #+begin_src haskell Run Locks #+end_src ** =CatInt n filename= - Reads and displays an integer from the file whose path is =filename= (especially useful with files in =/sys=). - Aliases as =catn= (e.g. =Cat 0= as =cat0=, etc.) so you can have several. - Example: #+begin_src haskell Run CatInt 0 "/sys/devices/platform/thinkpad_hwmon/fan1_input" [] 50 #+end_src ** =UVMeter= - Aliases to "uv" + station id. For example: =%uv Brisbane%= or =%uv Alice Springs%= - Args: default monitor arguments, plus: - =--useManager= /bool/ : Whether to use one single manager per monitor for managing network connections or create a new one every time a connection is made. - Short option: =-m= - Default: True - /Reminder:/ Keep the refresh rate high, to avoid making unnecessary requests every time the plug-in is run. - Station IDs can be found here: http://www.arpansa.gov.au/uvindex/realtime/xml/uvvalues.xml - Example: #+begin_src haskell Run UVMeter "Brisbane" ["-H", "3", "-L", "3", "--low", "green", "--high", "red"] 900 #+end_src * Interfacing with Window Managers Listed below are ways to interface xmobar with your window manager of choice. ** =XMonadLog= - Aliases to XMonadLog - Displays information from xmonad's =_XMONAD_LOG=. You can use this by using functions from the [[https://hackage.haskell.org/package/xmonad-contrib-0.16/docs/XMonad-Hooks-DynamicLog.html][XMonad.Hooks.DynamicLog]] module. By using the =xmonadPropLog= function in your logHook, you can write the the above property. The following shows a minimal xmonad configuration that spawns xmobar and then writes to the =_XMONAD_LOG= property. #+begin_src haskell main = do spawn "xmobar" xmonad $ def { logHook = dynamicLogString defaultPP >>= xmonadPropLog } #+end_src This plugin can be used as a sometimes more convenient alternative to =StdinReader=. For instance, it allows you to (re)start xmobar outside xmonad. ** =StdinReader= - Aliases to StdinReader - Displays any text received by xmobar on its standard input. - Strips actions from the text received. This means you can't pass dynamic actions via stdin. This is safer than =UnsafeStdinReader= because there is no need to escape the content before passing it to xmobar's standard input. ** =UnsafeStdinReader= - Aliases to UnsafeStdinReader - Displays any text received by xmobar on its standard input. - Will not do anything to the text received. This means you can pass dynamic actions via stdin. Be careful to escape (using =<raw=…>=) or remove tags from dynamic text that you pipe-thru to xmobar's standard input, e.g. window's title. - Sample usage: send to xmobar's stdin the list of your workspaces enclosed by actions tags that switches the workspaces to be able to switch workspaces by clicking on xmobar: #+begin_src shell <action=`xdotool key alt+1`>ws1</action> <action=`xdotool key alt+1`>ws2</action> #+end_src ** =UnsafeXMonadLog= - Aliases to UnsafeXMonadLog - Similar to =StdinReader= versus =UnsafeStdinReader=, this does not strip =<action ...>= tags from XMonad's =_XMONAD_LOG=. - It is advised that you still use =xmobarStrip= for the ppTitle in your logHook: #+begin_src haskell myPP = defaultPP { ppTitle = xmobarStrip } main = xmonad $ def { logHook = dynamicLogString myPP >>= xmonadPropLog } #+end_src ** =CommandReader "/path/to/program" Alias= - Runs the given program, and displays its standard output. ** =PipeReader "default text:/path/to/pipe" Alias= - Reads its displayed output from the given pipe. - Prefix an optional default text separated by a colon - Expands environment variables in the first argument of syntax =${VAR}= or =$VAR= ** =MarqueePipeReader "default text:/path/to/pipe" (length, rate, sep) Alias= - Generally equivalent to PipeReader - Text is displayed as marquee with the specified length, rate in 10th seconds and separator when it wraps around #+begin_src haskell Run MarqueePipeReader "/tmp/testpipe" (10, 7, "+") "mpipe" #+end_src - Expands environment variables in the first argument ** =BufferedPipeReader Alias [(Timeout, Bool, "/path/to/pipe1"), ..]= - Display data from multiple pipes. - Timeout (in tenth of seconds) is the value after which the previous content is restored i.e. if there was already something from a previous pipe it will be put on display again, overwriting the current status. - A pipe with Timeout of 0 will be displayed permanently, just like =PipeReader= - The boolean option indicates whether new data for this pipe should make xmobar appear (unhide, reveal). In this case, the Timeout additionally specifies when the window should be hidden again. The output is restored in any case. - Use it for OSD-like status bars e.g. for setting the volume or brightness: #+begin_src haskell Run BufferedPipeReader "bpr" [ ( 0, False, "/tmp/xmobar_window" ) , ( 15, True, "/tmp/xmobar_status" ) ] #+end_src Have your window manager send window titles to =/tmp/xmobar_window=. They will always be shown and not reveal your xmobar. Sending some status information to =/tmp/xmobar_status= will reveal xmonad for 1.5 seconds and temporarily overwrite the window titles. - Take a look at [[http://github.com/jaor/xmobar/raw/master/examples/status.sh][examples/status.sh]] - Expands environment variables for the pipe path ** =HandleReader Handle Alias= - Display data from a Haskell =Handle= - This plugin is only useful if you are running xmobar from another Haskell program like XMonad. - You can use =System.Process.createPipe= to create a pair of =read= & =write= Handles. Pass the =read= Handle to HandleReader and write your output to the =write= Handle: #+begin_src haskell (readHandle, writeHandle) <- createPipe xmobarProcess <- forkProcess $ xmobar myConfig { commands = Run (HandleReader readHandle "handle") : commands myConfig } hPutStr writeHandle "Hello World" #+end_src * Executing External Commands In order to execute an external command you can either write the command name in the template, in this case it will be executed without arguments, or you can configure it in the "commands" configuration option list with the Com template command: =Com ProgramName Args Alias RefreshRate= - ProgramName: the name of the program - Args: the arguments to be passed to the program at execution time - RefreshRate: number of tenths of second between re-runs of the command. A zero or negative rate means that the command will be executed only once. - Alias: a name to be used in the template. If the alias is en empty string the program name can be used in the template. E.g.: #+begin_src haskell Run Com "uname" ["-s","-r"] "" 0 #+end_src can be used in the output template as =%uname%= (and xmobar will call /uname/ only once), while #+begin_src haskell Run Com "date" ["+\"%a %b %_d %H:%M\""] "mydate" 600 #+end_src can be used in the output template as =%mydate%=. Sometimes, you don't mind if the command executed exits with an error, or you might want to display a custom message in that case. To that end, you can use the =ComX= variant: =ComX ProgramName Args ExitMessage Alias RefreshRate= Works like =Com=, but displaying =ExitMessage= (a string) if the execution fails. For instance: #+begin_src haskell Run ComX "date" ["+\"%a %b %_d %H:%M\""] "N/A" "mydate" 600 #+end_src will display "N/A" if for some reason the =date= invocation fails. * The DBus Interface When compiled with the optional =with_dbus= flag, xmobar can be controlled over dbus. All signals defined in [[https://github.com/jaor/xmobar/blob/master/src/Xmobar/System/Signal.hs][src/Signal.hs]] as =data SignalType= can now be sent over dbus to xmobar. Due to current limitations of the implementation only one process of xmobar can acquire the dbus. This is handled on a first-come-first-served basis, meaning that the first process will get the dbus interface. Other processes will run without further problems, yet have no dbus interface. - Bus Name: =org.Xmobar.Control= - Object Path: =/org/Xmobar/Control= - Member Name: Any of SignalType, e.g. =string:Reveal= - Interface Name: =org.Xmobar.Control= An example using the =dbus-send= command line utility: #+begin_src shell dbus-send \ --session \ --dest=org.Xmobar.Control \ --type=method_call \ --print-reply \ '/org/Xmobar/Control' \ org.Xmobar.Control.SendSignal \ "string:Toggle 0" #+end_src It is also possible to send multiple signals at once: #+begin_src shell # send to another screen, reveal and toggle the persistent flag dbus-send [..] \ "string:ChangeScreen 0" "string:Reveal 0" "string:TogglePersistent" #+end_src The =Toggle=, =Reveal=, and =Hide= signals take an additional integer argument that denotes an initial delay, in tenths of a second, before the command takes effect. ** Example for using the DBus IPC interface with XMonad Bind the key which should {,un}map xmobar to a dummy value.

#+OPTIONS: toc:t * System Monitor Plugins This is the description of the system monitor plugins available in xmobar. Some of them are only installed when an optional build option is set: we mention that fact, when needed, in their description. Each monitor has an =alias= to be used in the output template. Monitors may have default aliases, see the documentation of the monitor in question. There are two types of arguments: ones that all monitors share (the so called /default monitor arguments/) and arguments that are specific to a certain monitor. All Monitors accept a common set of arguments, described below in [[Default Monitor Arguments]]. Some monitors also accept additional options that are specific to them. When specifying the list of arguments in your configuration, the common options come first, followed by =--=, followed by any monitor-specific options. ** Icon patterns Some monitors allow usage of strings that depend on some integer value from 0 to 8 by replacing all occurrences of =%%= with it (i.e. == will be interpreted as == when the value is =3=, also =%= is interpreted as =%=, =%%= as =3=, =%%%= as =3%=, =%%%%= as =33= and so on). Essentially it allows to replace vertical bars with custom icons. For example, #+begin_src haskell Run Brightness [ "-t", "" , "--" , "--brightness-icon-pattern", "" ] 30 #+end_src Will display =bright_0.xpm= to =bright_8.xpm= depending on current brightness value. ** Default Monitor Arguments These are the options available for all monitors: - =-t= /string/ Output template - Template for the monitor output. Field names must be enclosed between pointy brackets (==) and will be substituted by the computed values. You can also specify the foreground (and optionally, background) color for a region by bracketing it between == (or ==) and ==. The rest of the template is output verbatim. - Long option: =--template= - Default value: per monitor (see above). - =-H= /number/ The high threshold. - Numerical values higher than /number/ will be displayed with the color specified by =-h= (see below). - Long option: =--High= - Default value: 66 - =-L= /number/ The low threshold. - Numerical values higher than /number/ and lower than the high threshold will be displayed with the color specified by =-n= (see below). Values lower than /number/ will use the =-l= color. - Long option: =--Low= - Default value: 33 - =-h= /color/ High threshold color. - Color for displaying values above the high threshold. /color/ can be either a name (e.g. "blue") or an hexadecimal RGB (e.g. "#FF0000"). - Long option: =--high= - Default: none (use the default foreground). - =-n= /color/ Color for 'normal' values - Color used for values greater than the low threshold but lower than the high one. - Long option: =--normal= - Default: none (use the default foreground). - =-l= /color/ The low threshold color - Color for displaying values below the low threshold. - Long option: =--low= - Default: none (use the default foreground). - =-S= /boolean/ Display optional suffixes - When set to a true designator ("True", "Yes" or "On"), optional value suffixes such as the '%' symbol or optional units will be displayed. - Long option: =--suffix= - Default: False. - =-p= /number/ Percentages padding - Width, in number of digits, for quantities representing percentages. For instance =-p 3= means that all percentages in the monitor will be represented using 3 digits. - Long option: =--ppad= - Default value: 0 (don't pad) - =-d= /number/ Decimal digits - Number of digits after the decimal period to use in float values. - Long option: =--ddigits= - Default value: 0 (display only integer part) - =-m= /number/ Minimum field width - Minimum width, in number of characters, of the fields in the monitor template. Values whose printed representation is shorter than this value will be padded using the padding characters given by the =-c= option with the alignment specified by =-a= (see below). - Long option: =--minwidth= - Default: 0 - =-M= /number/ Maximum field width - Maximum width, in number of characters, of the fields in the monitor template. Values whose printed representation is longer than this value will be truncated. - Long option: =--maxwidth= - Default: 0 (no maximum width) - =-e= /string/ Maximum width ellipsis - Ellipsis to be added to the field when it has reached its max width. - Long option: =--maxwidthellipsis= - Default: "" (no ellipsis) - =-w= /number/ Fixed field width - All fields will be set to this width, padding or truncating as needed. - Long option: =--width= - Default: 0 (variable width) - =-T= /number/ Maximum total width - Maximum total width of the text. - Long option: =--maxtwidth= - Default: 0 (no limit) - =-E= /string/ Maximum total width ellipsis - Ellipsis to be added to the total text when it has reached its max width. - Long option: =--maxtwidthellipsis= - Default: "" (no ellipsis) - =-c= /string/ - Characters used for padding. The characters of /string/ are used cyclically. E.g., with =-P +- -w 6=, a field with value "foo" will be represented as "+-+foo". - Long option: =--padchars= - Default value: " " - =-a= r|l Field alignment - Whether to use right (r) or left (l) alignment of field values when padding. - Long option: =--align= - Default value: r (padding to the left) - =-b= /string/ Bar background - Characters used, cyclically, to draw the background of bars. For instance, if you set this option to "·.", an empty bar will look like this: =·.·.·.·.·.= - Long option: =--bback= - Default value: ":" - =-f= /string/ Bar foreground - Characters used, cyclically, to draw the foreground of bars. - Long option: =--bfore= - Default value: "#" - =-W= /number/ Bar width - Total number of characters used to draw bars. - Long option: =--bwidth= - Default value: 10 - Special value: 0. When this parameter is 0, the percentage to display is interpreted as a position in the bar foreground string (given by =-f=), and the character at that position is displayed. - =-x= /string/ N/A string - String to be used when the monitor is not available - Long option: =--nastring= - Default value: "N/A" Commands' arguments must be set as a list. E.g.: #+begin_src haskell Run Weather "EGPF" ["-t", ": C"] 36000 #+end_src In this case xmobar will run the weather monitor, getting information for the weather station ID EGPF (Glasgow Airport, as a homage to GHC) every hour (36000 tenth of seconds), with a template that will output something like: #+begin_src shell Glasgow Airport: 16.0C #+end_src ** =Uptime Args RefreshRate= - Aliases to =uptime= - Args: default monitor arguments. The low and high thresholds refer to the number of days. - Variables that can be used with the =-t/--template= argument: =days=, =hours=, =minutes=, =seconds=. The total uptime is the sum of all those fields. You can set the =-S= argument to =True= to add units to the display of those numeric fields. - Default template: =Up: d h m= ** =Weather StationID Args RefreshRate= - Aliases to the Station ID: so =Weather "LIPB" []= can be used in template as =%LIPB%= - Thresholds refer to temperature in the selected units - Args: default monitor arguments, plus: - =--weathers= /string/ : display a default string when the =weather= variable is not reported. - short option: =-w= - Default: "" - =--useManager= /bool/ : Whether to use one single manager per monitor for managing network connections or create a new one every time a connection is made. - Short option: =-m= - Default: True - Variables that can be used with the =-t/--template= argument: =station=, =stationState=, =year=, =month=, =day=, =hour=, =windCardinal=, =windAzimuth=, =windMph=, =windKnots=, =windMs=, =windKmh= =visibility=, =skyCondition=, =weather=, =tempC=, =tempF=, =dewPointC=, =dewPointF=, =rh=, =pressure= - Default template: =: C, rh % ()= - Retrieves weather information from http://tgftp.nws.noaa.gov. Here is an [[https://tgftp.nws.noaa.gov/data/observations/metar/decoded/CYLD.TXT][example]], also showcasing the kind of information that may be extracted. ** =WeatherX StationID SkyConditions Args RefreshRate= - Works in the same way as =Weather=, but takes an additional argument, a list of pairs from sky conditions to their replacement (typically a unicode string or an icon specification). - Use the variable =skyConditionS= to display the replacement of the corresponding sky condition. All other =Weather= template variables are available as well.

The program writing the value of the read property is responsible of performing any needed cleanups. ** =NamedXPropertyLog PropName Alias= - Aliases to =Alias= - Same as =XPropertyLog=, but a custom alias can be specified. ** =UnsafeNamedXPropertyLog PropName Alias= - Aliases to =Alias= - Same as =UnsafeXPropertyLog=, but a custom alias can be specified. ** =Brightness Args RefreshRate= - Aliases to =bright= - Args: default monitor arguments, plus the following specif ones: - =-D=: directory in =/sys/class/backlight/= with files in it (default: "acpi_video0") - =-C=: file with the current brightness (default: actual_brightness) - =-M=: file with the maximum brightness (default: max_brightness) - =--brightness-icon-pattern=: dynamic string for current brightness in =ipat=. - Variables that can be used with the =-t/--template= argument: =vbar=, =percent=, =bar=, =ipat= - Default template: =<percent>= - Example: #+begin_src haskell Run Brightness ["-t", "<bar>"] 60 #+end_src ** =Kbd Opts= - Registers to XKB/X11-Events and output the currently active keyboard layout. Supports replacement of layout names. - Aliases to =kbd= - Opts is a list of tuples: - first element of the tuple is the search string - second element of the tuple is the corresponding replacement - Example: #+begin_src haskell Run Kbd [("us(dvorak)", "DV"), ("us", "US")] #+end_src ** =Locks= - Displays the status of Caps Lock, Num Lock and Scroll Lock. - Aliases to =locks= - Example: #+begin_src haskell Run Locks #+end_src ** =CatInt n filename= - Reads and displays an integer from the file whose path is =filename= (especially useful with files in =/sys=). - Aliases as =catn= (e.g. =Cat 0= as =cat0=, etc.) so you can have several. - Example: #+begin_src haskell Run CatInt 0 "/sys/devices/platform/thinkpad_hwmon/fan1_input" [] 50 #+end_src ** =UVMeter= - Aliases to "uv" + station id. For example: =%uv Brisbane%= or =%uv Alice Springs%= - Args: default monitor arguments, plus: - =--useManager= /bool/ : Whether to use one single manager per monitor for managing network connections or create a new one every time a connection is made. - Short option: =-m= - Default: True - /Reminder:/ Keep the refresh rate high, to avoid making unnecessary requests every time the plug-in is run. - Station IDs can be found here: http://www.arpansa.gov.au/uvindex/realtime/xml/uvvalues.xml - Example: #+begin_src haskell Run UVMeter "Brisbane" ["-H", "3", "-L", "3", "--low", "green", "--high", "red"] 900 #+end_src * Interfacing with Window Managers Listed below are ways to interface xmobar with your window manager of choice. ** =XMonadLog= - Aliases to XMonadLog - Displays information from xmonad's =_XMONAD_LOG=. You can use this by using functions from the [[https://hackage.haskell.org/package/xmonad-contrib-0.16/docs/XMonad-Hooks-DynamicLog.html][XMonad.Hooks.DynamicLog]] module. By using the =xmonadPropLog= function in your logHook, you can write the the above property. The following shows a minimal xmonad configuration that spawns xmobar and then writes to the =_XMONAD_LOG= property. #+begin_src haskell main = do spawn "xmobar" xmonad $ def { logHook = dynamicLogString defaultPP >>= xmonadPropLog } #+end_src This plugin can be used as a sometimes more convenient alternative to =StdinReader=. For instance, it allows you to (re)start xmobar outside xmonad. ** =StdinReader= - Aliases to StdinReader - Displays any text received by xmobar on its standard input. - Strips actions from the text received. This means you can't pass dynamic actions via stdin. This is safer than =UnsafeStdinReader= because there is no need to escape the content before passing it to xmobar's standard input. ** =UnsafeStdinReader= - Aliases to UnsafeStdinReader - Displays any text received by xmobar on its standard input. - Will not do anything to the text received. This means you can pass dynamic actions via stdin. Be careful to escape (using =<raw=…>=) or remove tags from dynamic text that you pipe-thru to xmobar's standard input, e.g. window's title. - Sample usage: send to xmobar's stdin the list of your workspaces enclosed by actions tags that switches the workspaces to be able to switch workspaces by clicking on xmobar: #+begin_src shell <action=`xdotool key alt+1`>ws1</action> <action=`xdotool key alt+1`>ws2</action> #+end_src ** =UnsafeXMonadLog= - Aliases to UnsafeXMonadLog - Similar to =StdinReader= versus =UnsafeStdinReader=, this does not strip =<action ...>= tags from XMonad's =_XMONAD_LOG=. - It is advised that you still use =xmobarStrip= for the ppTitle in your logHook: #+begin_src haskell myPP = defaultPP { ppTitle = xmobarStrip } main = xmonad $ def { logHook = dynamicLogString myPP >>= xmonadPropLog } #+end_src ** =CommandReader "/path/to/program" Alias= - Runs the given program, and displays its standard output. ** =PipeReader "default text:/path/to/pipe" Alias= - Reads its displayed output from the given pipe. - Prefix an optional default text separated by a colon - Expands environment variables in the first argument of syntax =${VAR}= or =$VAR= ** =MarqueePipeReader "default text:/path/to/pipe" (length, rate, sep) Alias= - Generally equivalent to PipeReader - Text is displayed as marquee with the specified length, rate in 10th seconds and separator when it wraps around #+begin_src haskell Run MarqueePipeReader "/tmp/testpipe" (10, 7, "+") "mpipe" #+end_src - Expands environment variables in the first argument ** =BufferedPipeReader Alias [(Timeout, Bool, "/path/to/pipe1"), ..]= - Display data from multiple pipes. - Timeout (in tenth of seconds) is the value after which the previous content is restored i.e. if there was already something from a previous pipe it will be put on display again, overwriting the current status. - A pipe with Timeout of 0 will be displayed permanently, just like =PipeReader= - The boolean option indicates whether new data for this pipe should make xmobar appear (unhide, reveal). In this case, the Timeout additionally specifies when the window should be hidden again. The output is restored in any case. - Use it for OSD-like status bars e.g. for setting the volume or brightness: #+begin_src haskell Run BufferedPipeReader "bpr" [ ( 0, False, "/tmp/xmobar_window" ) , ( 15, True, "/tmp/xmobar_status" ) ] #+end_src Have your window manager send window titles to =/tmp/xmobar_window=. They will always be shown and not reveal your xmobar. Sending some status information to =/tmp/xmobar_status= will reveal xmonad for 1.5 seconds and temporarily overwrite the window titles. - Take a look at [[http://github.com/jaor/xmobar/raw/master/examples/status.sh][examples/status.sh]] - Expands environment variables for the pipe path ** =HandleReader Handle Alias= - Display data from a Haskell =Handle= - This plugin is only useful if you are running xmobar from another Haskell program like XMonad. - You can use =System.Process.createPipe= to create a pair of =read= & =write= Handles. Pass the =read= Handle to HandleReader and write your output to the =write= Handle: #+begin_src haskell (readHandle, writeHandle) <- createPipe xmobarProcess <- forkProcess $ xmobar myConfig { commands = Run (HandleReader readHandle "handle") : commands myConfig } hPutStr writeHandle "Hello World" #+end_src * Executing External Commands In order to execute an external command you can either write the command name in the template, in this case it will be executed without arguments, or you can configure it in the "commands" configuration option list with the Com template command: =Com ProgramName Args Alias RefreshRate= - ProgramName: the name of the program - Args: the arguments to be passed to the program at execution time - RefreshRate: number of tenths of second between re-runs of the command. A zero or negative rate means that the command will be executed only once. - Alias: a name to be used in the template. If the alias is en empty string the program name can be used in the template. E.g.: #+begin_src haskell Run Com "uname" ["-s","-r"] "" 0 #+end_src can be used in the output template as =%uname%= (and xmobar will call /uname/ only once), while #+begin_src haskell Run Com "date" ["+\"%a %b %_d %H:%M\""] "mydate" 600 #+end_src can be used in the output template as =%mydate%=. Sometimes, you don't mind if the command executed exits with an error, or you might want to display a custom message in that case. To that end, you can use the =ComX= variant: =ComX ProgramName Args ExitMessage Alias RefreshRate= Works like =Com=, but displaying =ExitMessage= (a string) if the execution fails. For instance: #+begin_src haskell Run ComX "date" ["+\"%a %b %_d %H:%M\""] "N/A" "mydate" 600 #+end_src will display "N/A" if for some reason the =date= invocation fails. * The DBus Interface When compiled with the optional =with_dbus= flag, xmobar can be controlled over dbus. All signals defined in [[https://github.com/jaor/xmobar/blob/master/src/Xmobar/System/Signal.hs][src/Signal.hs]] as =data SignalType= can now be sent over dbus to xmobar. Due to current limitations of the implementation only one process of xmobar can acquire the dbus. This is handled on a first-come-first-served basis, meaning that the first process will get the dbus interface. Other processes will run without further problems, yet have no dbus interface. - Bus Name: =org.Xmobar.Control= - Object Path: =/org/Xmobar/Control= - Member Name: Any of SignalType, e.g. =string:Reveal= - Interface Name: =org.Xmobar.Control= An example using the =dbus-send= command line utility: #+begin_src shell dbus-send \ --session \ --dest=org.Xmobar.Control \ --type=method_call \ --print-reply \ '/org/Xmobar/Control' \ org.Xmobar.Control.SendSignal \ "string:Toggle 0" #+end_src It is also possible to send multiple signals at once: #+begin_src shell # send to another screen, reveal and toggle the persistent flag dbus-send [..] \ "string:ChangeScreen 0" "string:Reveal 0" "string:TogglePersistent" #+end_src The =Toggle=, =Reveal=, and =Hide= signals take an additional integer argument that denotes an initial delay, in tenths of a second, before the command takes effect. ** Example for using the DBus IPC interface with XMonad Bind the key which should {,un}map xmobar to a dummy value. This is necessary for {,un}grabKey in xmonad. #+begin_src haskell ((0, xK_Alt_L), pure ()) #+end_src Also, install =avoidStruts= layout modifier from =XMonad.Hooks.ManageDocks= Finally, install these two event hooks (=handleEventHook= in =XConfig=) =myDocksEventHook= is a replacement for =docksEventHook= which reacts on unmap events as well (which =docksEventHook= doesn't). #+begin_src haskell import qualified XMonad.Util.ExtensibleState as XS data DockToggleTime = DTT { lastTime :: Time } deriving (Eq, Show, Typeable) instance ExtensionClass DockToggleTime where initialValue = DTT 0 toggleDocksHook :: Int -> KeySym -> Event -> X All toggleDocksHook to ks ( KeyEvent { ev_event_display = d , ev_event_type = et , ev_keycode = ekc , ev_time = etime } ) = io (keysymToKeycode d ks) >>= toggleDocks >> return (All True) where toggleDocks kc | ekc == kc && et == keyPress = do safeSendSignal ["Reveal 0", "TogglePersistent"] XS.put ( DTT etime ) | ekc == kc && et == keyRelease = do gap <- XS.gets ( (-) etime . lastTime ) safeSendSignal [ "TogglePersistent" , "Hide " ++ show (if gap < 400 then to else 0) ] | otherwise = return () safeSendSignal s = catchX (io $ sendSignal s) (return ()) sendSignal = withSession . callSignal withSession mc = connectSession >>= \c -> callNoReply c mc >> disconnect c callSignal :: [String] -> MethodCall callSignal s = ( methodCall ( objectPath_ "/org/Xmobar/Control" ) ( interfaceName_ "org.Xmobar.Control" ) ( memberName_ "SendSignal" ) ) { methodCallDestination = Just $ busName_ "org.Xmobar.Control" , methodCallBody = map toVariant s } toggleDocksHook _ _ _ = return (All True) myDocksEventHook :: Event -> X All myDocksEventHook e = do when (et == mapNotify || et == unmapNotify) $ whenX ((not `fmap` (isClient w)) <&&> runQuery checkDock w) refresh return (All True) where w = ev_window e et = ev_event_type e #+end_src
